That's what I did and it's so much easier than tapping over at the ECU like a different wiring diagram I found suggested. I had to run the cables around 6" since they were mounted over the defroster vent rather than the width of the car.
Also, instead of using a galley plug and disconnecting the stock pressure sensor, I went with a Mishimoto sandwich plate. It was on Amazon for less than $30. My goal was to keep things all together.
